Daddy's home, and he is fucking pissed. Seems he is completely rushdown with only 1-2 projectiles, everything else is just hard hits and rushdown. Also seems to have a Rapid Cancel like mechanic to cancel any attack in a combo, which can lead to nutty combos.

Nael Deus Darnus has been available for 4+ years, and most people watch the story related to Binding Coils, I'd say the spoiler stuff with them has passed.
And you COULD use Zenos without too much spoilers, but yeah, Alphinaud would also allow the opportuinity to show the OTHER brand new class they made up for FFXIV (Arcanist), since Conjurer was shown with Y'shtola.

FULL DISCLOSURE: I have never played FFXII and know nothing about it besides the "I'm Captain Basch" meme.

I'm honestly really disappointed, FFXII already had a Chaos rep in the form of Gabranth (AND HE WAS THE FRICKIN' LOGO FOR FFXII), so instead of making up a Chaos rep for a game that still doens't have one, they just made another for FFXII to cover the fact they need to rework Gabranth?
Laaaaaaaaaaaaame.
My opinion is likely to change once I play FFXII

Vayne is honestly one of my favorite Final Fantasy villains entirely, if that helps
He's a genuinely charismatic and complex take on the usual evil emperor/conquerer type you see in the series
